An aircraft is flying at an altitude where the ambient pressure and temperature are 35 kPa and -15C, respectively. The freestream velocity is 1200 km/hr. The inlet diffuser (A2 / A1 = 1.3) slows the air to 85 m/s. Assuming air behaves as an idea gas and constant gas properties, what are the static pressure and temperature of the air at the exit to the diffuser?
